CORROSION INHIBITORS FOR REINFORCED CONCRETE: EFFECT OF ORGANIC SUBSTANCES
Corrosion of steel reinforcement is the most prominent cause of premature failure in reinforced concrete structures. The use of corrosion inhibitors seems to offer a simple and cost effective prevention technique against chloride induced corrosion; however, performance of commercial inhibitors available on the market is only partially satisfactory. This paper describes a basic study on organic substances which possess inhibiting effects on carbon steel corrosion. Test results on the effect of functional groups, obtained in simulated concrete pore solution and concrete slab tests, are discussed. The inhibition effect on corrosion initiation and propagation was evaluated by means of 2 electrochemical parameters: potential and polarization resistance. Tests on concrete specimens confirmed the effectiveness of some organic substances in delaying corrosion initiation and increasing the chloride concentration threshold.
